Jacques Seligmann & Co. was founded in Paris in 1880 by Jacques Seligmann (1858–1923), a German émigré who became a French citizen. His brothers Simon and Arnold, joined the gallery around 1900. They opened a New York branch in 1904. In 1912, after a family dispute, Arnold took over the French branch as Arnold Seligmann & Co., and established branches in the US in 1921 and Germany in 1932.
Seligmann sold Whistler's Arrangement in Black and Gold: Comte Robert de Montesquiou-Fezensac y398 to the American gambler and collector, Richard Canfield.
